TESTING:
OPTIONS:
Testing the electrical resistance of a winding is essential and is performed to measure the resistance of a winding.
The DC insulation resistance test evaluates the quality of the insulators, the possible presence of humidity and pollution.
The AC dielectric strength test is performed by setting an acceptability threshold of the maximum current.
The polarization index represents one of the most significant parameters to monitor the health of an engine, with reference to the condition of its insulators.
The SURGE test is the most reliable method to test the insulation of winding systems and can also be used to test partial discharges.
Partial discharges (PD) are electrical discharges localized in the dielectric insulation, limited only to a part of the dielectric material.
